into complex 3D views
The intelligent solution for support planning
LISEGA’s unique modular system was the
prerequisite for the creation of highly sophisticated
user software. The solutions on hand
open up new opportunities for increased
engineering design efficiency, improved quality
and significant savings in project manhours.
The general introduction of 2D and 3D CAD
modelling has already had a dramatic effect
on the design process for pipework systems.
However, the benefits for pipe support design
have been limited because supports were not
included in the 3D CAD programs.
The LICAD® program has set new standards in
this field. It allows the generation of pipe support
drawings, bills of materials and 3-D
models in minutes rather than hours. LICAD is
an intelligent front-end program that provides
all the required interface data for all common
CAD software programs from a single source.
From the point of view of quality this single
source function cannot be overemphasised.
To exploit further fields of application for
the LICAD user, LISEGA has also developed
supplementary software. The complete package
includes:
➜ LICAD planning and design software for
pipe supports
➜ EASYSTEEL design program for
secondary steel
➜ import and export interfaces for tables
and databases
➜ interfaces with 3D CAD component
packages
➜ 2D / 3D libraries for different CAD
programs
➜ interfaces to independent 3D
viewer programs
➜ Internet communication systems for
downloading program updates and
transmitting project information
including drawings and orders

LICAD
SOFTWARE WITH PROFIT EFFECT
Needed first - designed last
As a rule, the planning and design of complex
pipe systems runs through numerous
phases of optimization. Inevitably, the design
of pipe supports takes place at the end of
the whole process, and therefore often
comes too late to ensure prompt delivery.
Although the supports are needed on site
beforehand in order to ensure optimum
installation of the piping, they lie right at
the end of the planning chain.
At this point, it is even more vital to avoid
unnecessary delay. The time factor is now all
important.
LICAD speeds up the planning process
LICAD, the unique LISEGA design program
for pipe supports, sets the highest standards
in efficiency. With LICAD, poring over catalogs
and the painstaking preparation of bills of
material can be dispensed with. The design
of supports and load chains no longer needs
to be configured manually and then drawn
up at great expense in time and money.
What otherwise takes hours to produce can
be done in minutes electronically - at the
click of a mouse!
Future orientated logistics
Via LICAD, savings in time are possible in
the logistics process from planning right
through to delivery. For example, if required
the LICAD data can be sent directly by a
customer to our main
computer system for order processing on the
same day. This fits in well with ever tighter
order schedules!

LICAD is simple to use
The relevant data for individual support
points is entered using a menu driven program
control. Only 6 parameters are required
in order to find the optimum solution.
➜ pipe diameter
➜ temperature of the medium
➜ operating load
➜ travel
➜ installation height
➜ support configuration
From this input, the appropriate load chains
are created automatically and in fractions of
a second. The optimum selection of variable
spring and constant hangers is made by the
program simultaneously. Specific customer
requirements, such as travel and load reserves
in accordance with ASME, B 31.3, VGB or other
codes, are taken into account. This is provided
for by the corresponding input in a special
menu. Considering these requirements,
the programmed algorithm always ensures
that the most economical solution will be
selected from the possible options.
True to scale drawings
The support chains created are automatically
saved as complete assemblies and can be
printed or plotted as a drawing at any time.
They are true to scale and contain all
relevant details, including parts lists with
weights and material, and if required, pricing
and location plan.
LISEGA modular system forms the basis
A database system forms the basis of the
program which the complete LISEGA product
range is incorporated into as a functional
modular system. From more than 8000 standard
items, compatible herein with regard to
loads and connections, more than 100 standard
configurations cover practically any
installation situation.

Auxiliary steelwork
LICAD creates ready to install load chains
from standard supports, from the building
connection right through to the pipesurrounding
attachment. In order to produce
the connection to the existing structure,
supplementary auxiliary structures are frequently
required.
Via a special interface, the appropriate LICAD
designs are transferred to a separate CAD
program (e.g. AutoCAD), where they can be
supplemented as desired. In most cases,
where designs are not to complicated,
EASYSTEEL (see page 8.5) offers the ideal
solution.
Detailed display in 3D models
Interference checks
For larger plant projects, the design of the
building structure, including steelwork, main
components and piping, is carried out via
3D CAD programs, such as PDS/Microstation
(Intergraph), Plant Space (Bentley) or PDMS
(CADCENTRE). Planning continuity, as well as
the need to consider possible interferences,
necessitate the inclusion of the pipe supports
in the process. Using defined interfaces,
LICAD support designs can be transferred
with no additional effort three-dimensionally
and true to scale into the leading CAD
programs .
The standard LICAD drawings are automatically
transposed into 3D using special data files.
LICAD saves up to 50% of planning costs
LICAD runs smoothly on any modern PC with
Windows and is easy to use. Due to its particular
effectiveness, LICAD has already become
an indispensable tool for numerous engineering
departments when designing supports.
Potential cost savings of up to 50% simply
cannot be ignored!

EASYSTEEL
The ideal task when designing
pipe supports is to connect
a pipe directly to the
existing plant structure.
However, due to the given
support positions, in most
cases the existing plant
structure does not allow a
suitable connenction. The
support designer is then
required to plan additional
secondary steel, so-called
auxiliary structures.

attachment and connecting
options

Standard supports
With LICAD, the most appropriate support
configurations in each case are determined,
then the corresponding standard supports in
all their individual elements selected. A support
drawing, parts list and 3D model can all
be automatically generated using this
system. If the standard supports cannot be
connected directly to the existing plant structure,
the next step is to use additional steel
elements for the necessary adaptation.
Planning secondary steel
Although this steel may consist of only 1 or
2 items, each design is invariably unique, its
manufacture being both labour-intensive and
costly using traditional techniques.
Creating the design and producing a drawing
and a bill of materials with the cut lengths
and economic load calculations requires a
significant amount of time, even for simple
designs.
With EASYSTEEL, LISEGA has now developed
a powerful tool to reduce this time to a minimum
and improve the quality of the design
process. At the same time it ensures interface
compatibility for electronic integration. The
new LISEGA EASYSTEEL design program is a
logical complement to the LISEGA modular
system and the LICAD program.

The program can be used either independently
or in conjunction with data imported
from a LICAD file. The user is guided menucontrolled
through the design process, using
easy selection screens.
EASYSTEEL provides the user with the most
frequently used forms of steel designs as
basic elements. The most common connection
types are also supplied. The user selects
the appropriate design shape from the corresponding
selection screens and puts in
the relevant dimensions and interface data.
The program then suggests beam sizes that
are compatible in dimension and loading
with the LISEGA attachment component. A
further feature is the possibility of adaptation
to the surrounding structure.
After the user has decided on the preferred
section size, the program generates a true
to scale drawing with bill of materials and
cut list.
For the design elements available, EASY-
STEEL contains a series of load capacity
data bases. The information needed for the
design-related selection of frame elements
regarding weld sizes or bolt dimensions can
be found here.

Beam systems
The program allows the selection of beam
arrangements most commonly used for
secondary steel designs as standard:
➜ beam between two
existing structures
➜ cantilever types
➜ post types
Loading of beams is possible from above
or below.
Section sizes
The program uses virtual section sizes and
covers a sufficiently wide range of commonly
used beam sections for various countries.
The list of programed beam sections considers
American, European, Japanese and
Chinese standards. After determination of a
range of suitable steel sizes the designer can
decide which national standards shall be
used to generate the drawings.
Due to the modular program, and the use of
virtual section sizes, further specific national
standards can be included.
This system allows the flexibility to
design independently of specific national
standards.
Ranges of selected section sizes

Attachment to existing structure
The most common techniques for attachment
to the existing structure are available in the
program:
➜ beam directly welded
➜ beam with shim plates or beam with
end-plate to spread the load
➜ beam with bolt-on plates
➜ welded clip-angle connections
➜ cut-out flange connection to fit inbetween
two beams (with or without end/shim plate)
➜ beam end support on or under a roof
girder.
Weld sizes
The weld sizes selected by the program are
load compatible with the LISEGA modular
system whether the weld is measured in
throat thickness (mm) or leg length (inch,
acc. to American standard).
Weld sizes
Throat thickness 3 56 7 9 11 13 mm
Leg length 3/16 1/4 5/16 3/8 1/2 5/8 3/4 inch
Connection compatibility
Geometric checks are performed to avoid
designs which would not fit when assembled
on site. These checks include:
1. for welded attachments:
➜ comparison of the width of the attachment
(incl. weld seam) with beam width
➜ determination of the weld size suitable
for the section and attachment according to
prevailing rules and recommendations
2. for bolted connections:
➜ selection of section sizes that allow compatibility
of bolt holes with each other

How the program works
The program is database driven, working with
load capacity tables to determine the correct
section, bolting and weld sizes. The concept
allows the addition of other national section
standards.
Codes and regulations
The permissible load values used to select
beam and weld sizes are based on commonly
recognized steelwork codes such as AISC, BS,
DIN. Additionally, user specifications can be
defined and considered during the selection
process.
USE OF THE PROGRAM
User input
The program requires the following inputs:
➜ type designation of the attachment part
➜ operating load acting on the beam
➜ notation of the connection point
This input can be taken directly from the
LICAD file.
Four continuous screens guide the user in
defining:
➜ positioning of the attachment
➜ the beam system
➜ the necessary length information
➜ the type of connection to surrounding
structure
The scaled drawing includes all dimensions
and the bill of material. The weld sizes are
shown according to requirements in throat
thickness (mm) or leg length (inch). The language
desired can be selected from a range
of the most common languages.
